A new white paper from Rockwell Automation highlights the dangers of arc flash. The paper discusses the standards guiding arc-flash safety and details the role that arc-resistant motor-control centres (MCCs) play in helping to contain arc energy and reduce hazards.'Advances in low-voltage MCC technology help reduce arc-flash hazards and minimise risks' discusses how changing industry standards are putting more focus on arc-flash risks and highlights the key features and components of an effective arc-resistant MCC design. The paper stresses the importance of understanding the performance criteria that must be met before an MCC can be classified as an arc-resistant design.
According to the paper, an arc-resistant MCC is designed and built to provide a complete structural solution in accordance with defined industry standards. Arc-resistant equipment is designed to minimise arc-flash exposure by extinguishing the arc, controlling the spread of the arc or channelling the arc pressure and energy away from personnel.
